Quality Control

Our Cinnoline-4-Thiol is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are available upon request to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended long-term storage temperature is 2-8°C. Due to its sensitivity to oxidation, the container should be sealed immediately after use to minimize exposure to air.
